JBL Vibe flex Cleaning

Hi everyone!

I’ve had a JBL Vibe Flex earphone for about a year now, and it’s been great for workouts and phone calls.
Unfortunately, over time, it’s naturally gotten dirty, and the fabric covering the speaker has slowly clogged up. This has noticeably affected the volume and sound quality.

Since this model doesn’t have a removable fabric cover, I’m not sure how to clean it properly. Using a soft brush or cloth hasn’t helped much—they just end up pushing the earwax deeper into the fabric.

I was considering trying soapy water or isopropyl alcohol since the product is water-resistant, but I wanted to check here first. Has anyone else had this issue? Any tips would be greatly appreciated!

Thanks in advance!
